## DESCRIPTION

The **libfsapfs\_get\_version**() function is used to retrieve the library version.

## RETURN VALUES

Most of the functions return NULL or -1 on error, dependent on the return type. For the actual return values see "libfsapfs.h".

## ENVIRONMENT

None

## FILES

None

## NOTES

libfsapfs can be compiled with wide character support (wchar\_t).

To compile libfsapfs with wide character support use: *./configure* *--enable-wide-character-type=yes*\
  or define: *\_UNICODE*\
  or *UNICODE*\
  during compilation.

*LIBFSAPFS\_WIDE\_CHARACTER\_TYPE*\
  in libfsapfs/features.h can be used to determine if libfsapfs was compiled with wide character support.
